4.1.6 Using Jumps
The jump allows the program to “jump” between different steps within it. This is useful for repeating
the same ramp/soak combination during extended cycle testing of product. When a jump is
programmed on a step, the program will first execute the step as a normal step; however, once the
step time is complete, the program will jump to the specified “jump to step” rather than continuing on
to the next step in the program. After all of the programmed jumps have been completed, the
program will then continue to the next sequential step in the program without making any further
jumps.
To program a jump, enter the step number that you want the program to jump to when the step is
complete, along with the total number of jumps to be made. A cycle count of zero on a step indicates
that no jump will be made once the step is complete regardless of what the jump step number is set
to.
Jump to Step: Sets the step number that the program will jump to upon the completion of the step.
The program will only jump to this step if the cycle count is greater than zero.
Cycle Count: Sets the number of jumps that will be made from the step. Once all jumps have been
made, the program will continue on to the next step in sequential order.
The cycle count defines how many jumps will be made. Thus, if you wish to perform 10
cycles within a program, your cycle count will be set to 9, 10 minus the 1 performed prior to
reaching the jump step.
Example:
Product is to be loaded into the test chamber at ambient conditions, cycled b85 and -40 for
10 cycles, and then returned to ambient temperature, so that it can be removed in order to load the
next test sample.
Step 1 Start at +25
Step 2 Ramp to +85
Step 3 Soak at +85
Step 4 Ramp to -40
Step 5 Soak at -40
Set Jump to Step=2
Set Cycle Count=9
Step 6 End at +25
With the jump programmed on step 5, the program will jump from step 5 back to step 2 after the soak
time has completed. The program will then repeat steps 2 through 5. It will continue to do this until
all 9 jumps have occurred. Once all 9 jumps have been completed, the program will continue on to
step 6 after the final soak at -40. Since 1 cycle is made prior to the first jump at the end of step 5, a
total of 10 cycles are completed.
